Abstract: The present disclosure relates to an image-based component measurement system using a light unit that outputs a variable wavelength, a method thereof, and a plant cultivation method using the same. More specifically, the present disclosure provides an image-based component measurement system using a light unit that outputs a variable wavelength, a method thereof, and a plant cultivation method using the same, which collect and analyze data based on image information acquired by emitting light having a specific wavelength using a sheet on which a plurality of quantum dots which can be controlled to have a wavelength necessary for measuring a configuration component of a target object are arranged. Thus, the system and methods are able to measure component content contained in the target object using a low cost and miniaturized device, and cultivate a plant by adjusting content of nutrients of the plant using the measured component content.

Abstract: An apparatus for providing an optimal pest control recipe depending on a progress of disease and pest damages and a method thereof are provided. The apparatus for providing an optimal pest control recipe depending on a progress of disease and pest damages, in which the apparatus is connected with an photographing device and a user terminal, may include: an input module configured to receive image data of crops from the photographing device; a diagnosis module configured to analyze the image data to determine a type and progress of the disease and pest damages; a prescription module configured to generate a pest control recipe according to the determined progress of the disease and pest damages; and a communication module configured to transmit the pest control recipe to the user terminal.

Abstract: A lighting device is provided. The lighting device includes: a lighting unit in which a plurality of light sources are mounted; a lighting cover installed to be spaced apart from the lighting unit; and a reflective sheet arranged on a light source mounting surface of the lighting unit and reflecting reflected light reflected from the lighting cover back toward the lighting cover, wherein wavelength conversion layer for converting a wavelength of the reflected light reflected from the lighting cover is laminated on the reflective sheet.

Abstract: The present disclosure relates to a sunlight converting device including a wavelength converting film using a wavelength conversion material such as a quantum dot or an inorganic phosphor. More particularly, the present disclosure provides a sunlight converting device including a wavelength converting film using a wavelength conversion material, which can optimize plant growth and provide improved plant quality by installing a wavelength converting film on which a wavelength conversion material is applied so as to be converted into a predetermined wavelength and output to a greenhouse, (glasshouse), a vinyl house or a microalga culture facility, varying the sunlight irradiation area of the wavelength converting film, and supplying light of various wavelengths required for species of plant including microalgae or growth cycles thereof.
